CalledProcessError:Command'（'grep'，'route'）'返回非零退出状态1

Question

Python3
OSX 10.13.2

我正在尝试制作FACEBOOK_WHITELIST，以便在收听webhook
时防止来自互联网的恶意攻击 我正在获取IP地址。这个命令非常简单，只需whois、pipe和{}。在

问题：

def test():
    import subprocess
    ps = subprocess.Popen(
        ["whois", "-h", "whois.radb.net", "--", "'-i origin AS32934'"],
        stdout=subprocess.PIPE,
        stderr=subprocess.STDOUT
    )
    output = subprocess.check_output(('grep', 'route'), stdin=ps.stdout)
    ps.wait()

追踪：

^{pr2}$

然后我尝试了更小的函数调用。他们两个都不是工作。 第一个是单引号中的单字符串

In [46]: ps = subprocess.Popen(["whois", "-h", "whois.radb.net", "--", "'-i origin AS32934'"])
    ...:
    ...:

In [47]: %  No entries found for the selected source(s).

第二种方法是将字符串拆分为多个双引号字符串

In [48]: ps = subprocess.Popen(["whois", "-h", "whois.radb.net", "--", "'-i", "origin", "AS32934'"])

In [49]: %  No entries found for the selected source(s).
%  No entries found for the selected source(s).
%  No entries found for the selected source(s).

我哪里错了？在

@让·弗朗索瓦·法布

In [49]: ps = subprocess.Popen(["whois", "-h", "whois.radb.net", "--", "-i", "origin", "AS32934"])

In [50]: %% Attribute name after "-i" is invalid or unsupported.


%  No entries found for the selected source(s).

Answer 1

ps = subprocess.Popen(["whois", "-h", "whois.radb.net", " ", "'-i origin AS32934'"])# Wrong

你引用最后一篇文章的尝试与Popen的引用是多余的。我无法测试，但您必须删除您添加的额外引号：

^{pr2}$

Popen检测参数中是否有空格，并根据需要自动引用。添加更多引号会使Popen添加更多引号，并且命令的参数是错误的。在

除非您需要分别传递每个参数，但由于您在第一个和最后一个参数中留下了引号，否则这样做的尝试也会失败。但这并不意味着：

ps = subprocess.Popen(["whois", "-h", "whois.radb.net", " ", "'-i", "origin", "AS32934'"]# Wrong

应该是

ps = subprocess.Popen(["whois", "-h", "whois.radb.net", " ", "-i", "origin", "AS32934"]
